  • Paperboard/polymer laminate for blister pack
    Patent number: 5091261
    Abstract: A laminate for blister pack applications is comprised of a paperboard substrate having a first printable surface and a second surface onto which there is applied a polymeric coating suitable for adhering the plastic blister to the paperboard. The polymeric coating comprises a coextrusion consisting of a polyolefin material such as low density polyethylene (LDPE) which gives good adhesion to the paperboard surface and an adhesive material such as an ethylene-methyl acrylate copolymer (EMA) which gives good adhesion to the plastic blister.

  • Measuring the surface of a roller by glossmeter
    Patent number: 4053237
    Abstract: The surface texture of plastic film cast against chill rolls may be accurately predicted from the roll surface texture while mounted in a roll finishing machine by correlating a glossmeter measurement of the roll surface to an experimentally determined functional relation between similar rolls and corresponding film product.Means are provided on the glossmeter test base to assure accurate orientation of the instrument relative to the cylindrical surface and axis of the test subject.
